Hello,

I hope you are doing fine, NIT is good but if you are not satisfied with it then you can take admission in NIT and then sideways can also prepare for JEE. From college side you are not going to get any help. You will have to manage on your own like the timings and all. College will go on as usual. So decide yourself if you would be able to manage both your college studies and your JEE Preparation simultaneously then go for it.

I hope you find this information helpful. I wish you all the best for your future.

Good Luck
